[Bug 1156073] Zypper DUP to 20191104 snapshot boots to 'grub_file_filters' not found / grub rescue

http://bugzilla.opensuse.org/show_bug.cgi?id=1156073 http://bugzilla.opensuse.org/show_bug.cgi?id=1156073#c7 --- Comment #7 from T Adams --- Neil and Michael, thanks once more for your efforts to help. Fortunately, I can get into the system, after locking the grub files named in the second post in this thread, above. FWIW, my current grub2 version is 2.02-50.1. For Neil: Yast --> Boot Loader --> Boot Loader Location --> Boot from Partition is checked. Also checked on this same screen are "Set active Flag in Partition Table for Boot Partition" and "Write generic Boot Code to MBR." For Michael: cat /etc/default/grub_installdevice /dev/disk/by-uuid/452bcebb-fb29-448f-81c0-70397fcf1274 activate generic_mbr # hexdump -n 512 -C /dev/sda 00000000 eb 63 90 8e d8 8e d0 bc 00 7c 89 e6 06 57 8e c0 |.c.......|...W..| 00000010 fb fc bf 00 06 b9 00 01 f3 a5 ea 1f 06 00 00 52 |...............R| 00000020 52 b4 41 bb aa 55 31 c9 30 f6 f9 cd 13 72 13 81 |R.A..U1.0....r..| 00000030 fb 55 aa 75 0d d1 e9 73 09 66 c7 06 8d 06 b4 42 |.U.u...s.f.....B| 00000040 eb 15 5a b4 08 cd 13 83 e1 3f 51 0f b6 c6 40 f7 |..Z......?Q...@.| 00000050 e1 52 50 66 31 c0 66 99 e8 66 00 80 01 00 00 00 |.RPf1.f..f......| 00000060 00 00 00 00 ff fa 90 90 f6 c2 80 74 05 f6 c2 70 |...........t...p| 00000070 74 02 b2 80 ea 79 7c 00 00 31 c0 8e d8 8e d0 bc |t....y|..1......| 00000080 00 20 fb a0 64 7c 3c ff 74 02 88 c2 52 be 80 7d |. ..d|<.t...R..}| 00000090 e8 17 01 be 05 7c b4 41 bb aa 55 cd 13 5a 52 72 |.....|.A..U..ZRr| 000000a0 3d 81 fb 55 aa 75 37 83 e1 01 74 32 31 c0 89 44 |=..U.u7...t21..D| 000000b0 04 40 88 44 ff 89 44 02 c7 04 10 00 66 8b 1e 5c |.@.D..D.....f..\| 000000c0 7c 66 89 5c 08 66 8b 1e 60 7c 66 89 5c 0c c7 44 ||f.\.f..`|f.\..D| 000000d0 06 00 70 b4 42 cd 13 72 05 bb 00 70 eb 76 b4 08 |..p.B..r...p.v..| 000000e0 cd 13 73 0d 5a 84 d2 0f 83 d8 00 be 8b 7d e9 82 |..s.Z........}..| 000000f0 00 66 0f b6 c6 88 64 ff 40 66 89 44 04 0f b6 d1 |.f....d.@f.D....| 00000100 c1 e2 02 88 e8 88 f4 40 89 44 08 0f b6 c2 c0 e8 |.......@.D......| 00000110 02 66 89 04 66 a1 60 7c 66 09 c0 75 4e 66 a1 5c |.f..f.`|f..uNf.\| 00000120 7c 66 31 d2 66 f7 34 88 d1 31 d2 66 f7 74 04 3b ||f1.f.4..1.f.t.;| 00000130 44 08 7d 37 fe c1 88 c5 30 c0 c1 e8 02 08 c1 88 |D.}7....0.......| 00000140 d0 5a 88 c6 bb 00 70 8e c3 31 db b8 01 02 cd 13 |.Z....p..1......| 00000150 72 1e 8c c3 60 1e b9 00 01 8e db 31 f6 bf 00 80 |r...`......1....| 00000160 8e c6 fc f3 a5 1f 61 ff 26 5a 7c be 86 7d eb 03 |......a.&Z|..}..| 00000170 be 95 7d e8 34 00 be 9a 7d e8 2e 00 cd 18 eb fe |..}.4...}.......| 00000180 47 52 55 42 20 00 47 65 6f 6d 00 48 61 72 64 20 |GRUB .Geom.Hard | 00000190 44 69 73 6b 00 52 65 61 64 00 20 45 72 72 6f 72 |Disk.Read.
